- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
你好,我在我的 WPF 应用程序中随机分配了一些按钮,如下所示:
partial class Window1
{
private void button3_Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("action 3");
}
void button2Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("action 2");
}
void button1Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("action 1");
}
public Window1()
{
this.InitializeComponent();
populateButtons();
}
public void populateButtons()
{
double xPos;
double yPos;
Random ranNum = new Random();
foreach (var routedEventHandler in new RoutedEventHandler[] { button1Click, button2Click, button3_Click })
{
Button foo = new Button();
Style buttonStyle = Window.Resources["CurvedButton"] as Style;
int sizeValue = 100;
foo.Width = sizeValue;
foo.Height = sizeValue;
xPos = ranNum.Next(200);
yPos = ranNum.Next(250);
foo.HorizontalAlignment = HorizontalAlignment.Left;
foo.VerticalAlignment = VerticalAlignment.Top;
foo.Margin = new Thickness(xPos, yPos, 0, 0);
foo.Style = buttonStyle;
foo.Click += routedEventHandler;
LayoutRoot.Children.Add(foo);
}
}
}
我设置了填充按钮的区域,如下所示:
int xPos;
int yPos;
xPos = ranNum.Next(239);
yPos = ranNum.Next(307);
foo.HorizontalAlignment = HorizontalAlignment.Left;
foo.VerticalAlignment = VerticalAlignment.Top;
foo.Margin = new Thickness(xPos, yPos, 0, 0);
我现在更愿意做的是为这个区域设置一个名为 viewbox1 的 View 框(原始的 eh!);)
有没有办法在后面的代码中做到这一点?

最佳答案
要将按钮添加到 ViewBox,您可以这样做:
public void populateButtons()
{
double xPos;
double yPos;
UniformGrid grid = new UniformGrid();
viewbox1.Child = grid;
Random ranNum = new Random();
foreach (var routedEventHandler in new RoutedEventHandler[] { button1Click, button2Click, button3_Click })
{
Button foo = new Button();
Style buttonStyle = Window.Resources["CurvedButton"] as Style;
int sizeValue = 100;
foo.Width = sizeValue;
foo.Height = sizeValue;
xPos = ranNum.Next(200);
yPos = ranNum.Next(250);
foo.HorizontalAlignment = HorizontalAlignment.Left;
foo.VerticalAlignment = VerticalAlignment.Top;
foo.Margin = new Thickness(xPos, yPos, 0, 0);
foo.Style = buttonStyle;
foo.Click += routedEventHandler;
grid.Children.Add(foo);
}
}
